A 40 mm diameter shaft is made of steel 50C4 (Sut 660 N/mm²) and has machined surface. The expected reliability is 99%. The theoretical stress concentration factor for the shape of the shaft is 1.6 and the notch sensitivity factor is 0.9. Determine the endurance limit of the shaft.
Swamee's equation provides an approximate solution for virtually any usual relative roughness and Reynolds number values. Despite being an approximation that combines the equation for the laminar regime with the Colebrooke-White equation, it presents results that are more applicable than the latter for the critical region (2000 < Re < 4000).

Merrill et al. (1965) in a series of classic experiments studied the flow of blood in capillary tubes of various diameters. The blood had a hematocrit of 39.3 and the temperature was 20°C. They measured the pressure drop as a function of the flow rate for five tube diameters ranging from 288 to 850 μm. When they expressed the measured pressure drops in terms of the wall shear stress, and the volumetric flow rates in terms of the reduced average velocity, all of the data for the various tube sizes formed, within the experimental accuracy, a single line as predicted by the Rabinowitsch equation expressed in terms of reduced average velocity. From their results they provide the following values of the Casson parameters at 20°C: τy = 0.0289 dynes cm−2 and s = 0.229 (dynes s cm−2)1/2. Using these values for τy and s, show that the equation below for reduced average velocity provides an excellent fit to their data summarized in the following table. (Wall shear stress) τw , dynes cm-2…
Water at 70 °F is to be passed through a 1 micron-thick, porous PE membrane of 25% porosity with an average pore diameter of 0.3 micron and an average tortuosity of 1.3. The pressure on the downstream and upstream sides of the membrane are 125 and 500 kPa, respectively. Estimate the flow rate of water through the membrane.

6) In a boiler installation coal is burnt at the rate of 1.9 x 10³ kg/hr and hot gases are generated at the rate of 18 kg per kg of coal burnt. Hot gases are at the temperature of 600 K and ambient air temperature is 300 K Different pressure losses in furnace grate, flues, bends and chimney are measured to be 6 mm, 5 mm, 3 mm, and 1 mm of water respectively. Hot gases leaving chimney have velocity equivalent to 1.2 mm of water column. Considering the actual natural draught to be 80% of theoretical draught determine the height and diameter of chimney.

The velocity of the mercury at T_∞=250 o C is U_∞=0.033m/sec, and it flows over the pipe bundle of D= 1.25 cm diameter and L=1.2m length. The ratio of the vertical and diagonal spacing distances for the pipes in the shifted plate arrangement is ST /D=SD /D= 1.405. It consists of a matrix with the number of pipe rows in the horizontal direction NL=60 and the number of pipe rows in the vertical direction NT=30. Pipe wall (surface) temperatures are kept at a uniform temperature of T_w=160 o C. Accordingly, find the average heat transfer coefficient, the total heat transfer coefficient from the mercury to the pipe bundle. (Variables: ST /D=SD /D= 0.75-1.975, U=0.02-0.07m/s, L=0.5-1.4m)
